Description We propose to conduct three 15 ks XMM observations of M33 to be coordinated with a NuSTAR Legacy Program. With these observations, we will study the distribution of X-ray binary (XRB) accretion states in an actively star-forming environment, and constrain the 0.3-40 keV spectrum and variability of the most luminous XRB in the Local Group, the ULX M33 X-8, as well as two other bright sources. Our survey area covers > 70% of the star-formation activity within the M33 disk and will uniquely provide a significant improvement in our knowledge of HMXB accretion states and the details of the accretion process in 10^39 erg-s ULXs, which have not yet been studied at >10 keV.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations.
Since Earth's atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
